(f)Spectrum of Iodine Deficiency Disorders (IDD)

-Diseases on the spectrum comprise goiter, cretinism, hypothyroidism, brain damage, abortion, stillbirth, mental retardation, psychomotor abnormalities, and auditory and speech impairment2.

--Diseases on the spectrum comprise goiter, cretinism, hypothyroidism, brain harm, abortion, stillbirth, mental retardation, psychomotor abnormalities, and auditory and speech impairment2. The majority of IDD's consequences are hidden and irreparable, although they can be avoided.
